ReflectionMatrix

ReflectionMatrix[v]
gives the matrix that represents reflection of points in a mirror normal to the vector v.

MORE INFORMATION

The reflection is in a mirror that goes through the origin.

ReflectionMatrix works in any number of dimensions. In 2D it reflects in a line; in 3D it reflects in a plane.
